Covid vaccine controversy: benefits outweigh harms worldwide

Although all vaccines have some side effects, experts suggest that you should not panic because the negative effects of the vaccine are less compared to the problem of blood clots in the organs that appear due to the covid-19 infection.

Covid epidemic, lockdown, ICU and lack of oxygen, PCR test, vaccination. About four years ago, the same word was being shouted around the world. The corona infection started spreading around the world in December, 2019 from the Wuhan province of China, bringing the entire human world to a standstill.

Covid vaccine controversy: benefits outweigh harms worldwide

The main weapon to get out of the covid-19 epidemic, which once started a series of lockdowns in the entire world, was the vaccine against corona. According to a study, the vaccine against Corona has saved the lives of about 140 million people worldwide. However, compared to the millions of people who have been vaccinated, it is not that there are no problems in some people. However, the negative effects of the vaccine are now widely discussed.

According to the data of the Ministry of Health and Population of Nepal, around one million people in Nepal have been confirmed to be infected with Covid-19 and 12 thousand 20 people have died.

More than 70 percent of the total population of Nepal got vaccinated against the corona virus in order to overcome the corona epidemic. AstraZeneca's CoviSild is one of the earliest and most widely used vaccines in Nepal. According to the data of the Ministry of Health, about 31 lakh doses of Covicild vaccine were administered in Nepal. The spokesperson of the ministry said that it was given to about 1.3 million people by first, second and third doses. Prakash Budhathoki said.

Along with the AstraZeneca vaccine, another vaccine that has been used in large quantities in Nepal is the Chinese company Sinopharm's Verocell. Along with this, a few lakh quantities of American vaccine Moderna, Johnson & Johnson and Pfizer also entered Nepal.

There is currently a huge uproar in the world over the serious side effects of vaccines, mainly AstraZeneca, Pfizer and Moderna. But, as various news sources claim, do all those who have been vaccinated against Corona have negative health problems?

AstraZeneca's CoviSild

AstraZeneca admitted in a legal document submitted to the UK High Court last February that a rare type of negative side effect could be seen from the vaccine produced and sold under various names, including CoviSild, Vaxzevria.

According to AstraZeneca, a rare type of negative problem called 'Thrombosis with Thrombocytopenia Syndrome' (TTS) may be seen in those who have been vaccinated against Corona. Due to this problem, blood clots in the organs as well as the amount of platelets in the blood decreases, due to which the person may die. This means that the company has admitted during the court process that the vaccine against corona that it has developed will have a very rare negative effect.

However, that does not mean that the same problem appears in all those vaccinated. Infectious disease specialist Dr. claimed to have been told about rare negative effects before this vaccine was administered to the public. Anup Subedi mentioned on his social network.

In his opinion, many lives were saved because of the rapid development of the vaccine against Covid. "Nepalese got the vaccine earlier than most other underdeveloped countries and tens of thousands of lives were saved," he wrote, "Unfortunately, today's newspapers don't show this big picture and people are muttering about things they don't want." It is said that because Covisild was cheap and effective, millions of lives were saved around the world. "Oxford University scientists have developed the technology to make such an effective vaccine cheaply and because that vaccine was able to be produced on a large scale in India, Nepalis were able to get vaccinated at the beginning," he said.

dr. The spokesperson of the Ministry of Health and Population agrees with Anup Subedi's statement. According to him, during the court proceedings abroad, it was only seen that the company that developed and produced the Covisild vaccine formally admitted that 1/2 of the people who receive it may have a rare type of negative effect. "It was known when the vaccine was developed that a very small number of rare types of problems can be seen when vaccinating Covicild," he said, "No one has died after 300,000 vaccinations have been given in Nepal." Therefore, this is not a situation to panic.'

According to him, questions have been raised about the AstraZeneca vaccine all over the world, so the Ministry has instructed the Vaccine Advisory Committee to study and give suggestions on how to address this issue. The issue that has come out now is not new. Yet we have asked the Vaccine Advisory Committee to study it. What does the committee suggest and we will take a concrete decision,' he said, 'but overall, the Nepali people who have been vaccinated should not panic.'

Dr. According to Subedi, after the introduction of the covid vaccine in Nepal, he did not see a rare type of negative effect on even one of the thousands of patients who came to him for treatment. However, he said that he has seen dozens of patients with pulmonary embolism due to corona infection.

Another infectious disease specialist Dr. According to Prabhat Adhikari, even though all vaccines have some negative effect, the negative effect of the vaccine was less compared to the problem of blood clotting in the organs seen due to Covid-19 infection. Therefore, there is no need to panic about the topic that is now in discussion.

According to Christina Pagel, a professor working at the Clinical Operational Research Unit of University College London in the UK, the first and cheapest vaccine that was allowed to be administered to people during the Corona epidemic was Estragene. "This vaccine was cheaper than Pfizer, easier to administer and didn't require very low temperature for storage," he wrote on social media. At the same time, the negative effects that can be seen after wearing it started to be discussed and studies were also done about it. But getting this vaccine was safer than getting Covid.'

In his words, according to the study based on the type of vaccine, it was estimated that by the end of 2021, it was possible to save millions of lives due to the AstraZeneca vaccine. "Currently, according to the development of the corona virus, it is difficult to modify the Astrazene vaccine compared to other mRNA vaccines such as Moderna and Pfizer. So three years after the Covid pandemic, more and better vaccines have come to the market. They are cheap, safe and easy to update,” she wrote, “so the AstraZeneca vaccine is no longer needed. However, by saying this, we should not forget its contribution in 2021. According to

AstraZeneca, the main reason for the company withdrawing its vaccine from the world market is due to the large number of developed vaccines that target the new variant of the Corona virus in the market. "We have decided to withdraw our vaccine from the market due to the oversupply of developed vaccines against COVID-19," the company said in a statement. Similarly, India's Serum Institute of India (SII) has stopped the production of Covisild from December 2021.

Pfizer and Moderna

The Pfizer and Moderna vaccines developed and produced by American pharmaceutical companies are among the most widely used vaccines in the world for preventing corona. These two vaccines were administered to millions of people in Nepal as well as millions of people in the world. This vaccine, developed in mRNA technology, is currently being produced targeting new variants of the developed corona.

Like AstraZeneca's vaccine, Pfizer's vaccine is not without controversy. However, as discussed, experts claim that Pfizer's vaccine has given people more solutions than problems. Opponents of vaccines have claimed that there is an increased risk of cancer in people who have received a vaccine based on mRNA technology, as well as a risk of cancer returning in those who have been cured. However, vaccine experts say that the basis to fully prove their claim has not been seen yet.

In those who have been vaccinated against corona based on mRNA technology, rare types of heart related problems 'myocarditis' (inflammation of the heart muscle) and 'pericarditis' (inflammation of the thin membrane surrounding the heart) may be seen. Myocarditis was more common in those who received the second dose of Moderna vaccine. This problem was especially seen in the youth group. However, according to the US Center for Disease Control (CDC), the effectiveness of the vaccine was and is greater than the problems seen after vaccination. However, the majority of such problems are cured after treatment.

Rare types of problems that can occur after both vaccinations have not been seen in millions of people. However, supporters of the vaccine have claimed that the company as well as experts are already aware of such a problem. However, the opponents of the vaccine say that they have magnified the problem seen in a few compared to the millions who have been vaccinated.

There is no doubt that due to the use of these two vaccines, millions of people in the world could be saved from complications and death due to corona infection. According to a study conducted by the World Health Organization, about 14 million lives have been saved due to the use of vaccines in Europe alone. Due to vaccination against Corona, deaths due to Corona in the age group of 70 to 79 years have decreased by 57 percent. Similarly, the risk of death has decreased by 54 percent in the age group of 60 to 69 years and by 52 percent in the age group of 50 to 59 years.


Does the AstraZeneca vaccine have a problem with blood clots in the organs and a decrease in the amount of platelets in the blood?

may appear. According to studies published in various scientific journals and the company that developed and produced the vaccine, this is an extremely rare type of problem. Only 1 or 2 out of 100,000 people who receive this vaccine may experience this type of problem.

Has AstraZeneca withdrawn all its vaccines from the global market? is a

. However, the company has not withdrawn the vaccine from the market due to a rare type of problem caused by the vaccine, as claimed on social media. On the other hand, AstraZeneca has withdrawn its vaccine as many other vaccines that are very successful against the new variant of the corona virus are readily available in the market.

Does corona vaccine cause cancer?

Studies and researches so far have not found the fact that cancer is caused by corona vaccination. However, studies are being done around the world on the long-term effects of this vaccine and need to continue.
