By Shalini Bhardwaj New Delhi [India], Medical expert Dr MV Padma Srivastava said there are rare cases of side effects from vaccines, adding that the percentage of side effects is "very low. Dr MV Padma Srivastava is currently the chair of Neurology Para Hospital, Gurugram and former HOD, Department of Neurology, AIIMS, who worked actively during the time of COVID19, “We see but the percentage is small, compared to the larger percentage that actually helps in preventing the biggest disease, UK In media reports, pharmaceutical company AstraZeneca said that the COV vaccines Covishield and Vaxzevria can, in very rare cases, cause thromboses thrombocytopenia syndrome (TTS). Referring to the report, Dr. Padma said, “I have also read the report which says that, in fact, this is happening, but I should say this when you are looking at it to protect a particular issue. Vaccines are being given whenever a vaccine is introduced to protect against a major health problem, in this case, I believe that in rare situations, vaccines have caused this TTS and they Some are protecting against very bad viral infections and some are spin-offs like viruses that cause fever.We see it but the percentage is so small that compared to the larger percentages they actually help prevent most disease,'' he said of the vaccines. He further cited the study conducted by ICMR related to Covid-19 vaccines, “I am talking about Covid, vaccines, these issues are emerging. I think this is a work in progress. I t is a science that we are understanding better. We also had a study by ICMR that actually looked at the vaccine rollout in our country.And these heart attack and stroke issues were not largely related to the vaccine rollout, this is the ICMR study, which has also been in the public domain. Regarding blood clotting due to COVID-19 infection, he said, "Definitely, it is a very relevant issue. If not now, but I must say, it seems like a distant past, but I It was just one and a half-two years ago, we were having a heated debate on all this and yes, COVID itself is a highly thermogenic condition and there is a lot of pathogenetics and pathophysiology to support it, that COVID infection refers to its effects on the vessel wall, rheology or hematologic conditions, and a whole host of immune-mediated inflammatory mechanisms that cause clotting in blood vessels. Hence both arterial clotting and venous clotting has become a problem, said Dr Sanjay K Rai, professor at the Center for Community Medicine, AIIMS Delhi, "for any medicine.There are a variety of side effects. In some, the clotting system gets disturbed and in some, platelets are reduced. In some cases the clot forms and in others it does not. These are very rare side effects. Due to these side effects it was banned for people under 50 years of age.When asked if there was any risk he said it had been two years since people had received the vaccine so "the likelihood of any risk is low" TTS thromboses are thrombocytopenia syndrome, which is one of the conditions where blood clots form. AstraZeneca has made an admission in court documents in connection with a case alleging that the vaccine it developed with the University of Oxford caused deaths and serious injuries in dozens of cases, according to multiple UK media reports. The Institute of India produced a COVID-19 vaccine called Covishield not using the mRNA platform. It has been prepared using the viral vector platform. In the vaccine, a chimpanzee adenovirus – ChAdOx1 – has been modified to make it capable of carrying the COVID-19 spike protein into human cells. This cold virus is basically incapable of infecting the receiver, but may very well teach the immune system to prepare a mechanism against such viruses. Amid reports in the UK media about clots in blood vessels, the Serum Institute of India did not respond to the question.In 2023, the World Health Organization (WHO) in its report stated that TT emerged as a new adverse event following vaccination in individuals vaccinated with COVID-19 non-replicating adenovirus vector-based vaccines.
