Haryana’s minister tests positive for Covid-19
Haryana’s Health Minister Anil Vij announced on Saturday that he tested positive for Covid-19, just over two weeks after he joined a vaccine trial and was given the first of two injections, which it may or may not have been the actual inoculation.
Vij’s disease and participation in Bharat Biotech’s Covaxin trial led to confusion about the vaccine, prompting the company to clarify that the injection should be protective only two weeks after the second dose, which in turn is administered. after an interval of 28 days after application. first dose. Subsequently, the minister himself addressed the concerns.
“They told me that the antibodies start to develop after the second dose, which is given within 28 days of receiving the first injection. And complete antibodies develop 14 days after the administration of the second dose. So the complete cycle takes 42 days. There is no protection in the middle, ”Vij said in a phone call to the PTI news agency.
Previously, he tweeted: “I tested positive for Corona. I am admitted to the Ambala Cantt Civil Hospital. All those who have been in close contact with me are advised to take the crown test, ”he tweeted.
Covaxin is a two-dose vaccine developed by the Indian vaccine manufacturer Bharat Biotech in collaboration with the government’s National Institute of Virology. It uses an inactivated virus to elicit an immune response in people.
The vaccine is currently in phase III trials, with more than 25,000 volunteers. According to the Bharat Biotech trial registry, half of these people will receive a placebo and half the vaccine. The trial is a randomized, double-blind experiment, meaning that neither Vij nor the officials would know if what they gave him was actually the vaccine.
Technically, you have a 50% chance of receiving the vaccine.
“It is a double-blind path (that is, neither the recipient nor the researchers know who receives a vaccine and who receives a placebo). These trials have a very rigorous protocol for unmasking, ”said an official from the Union Ministry of Health, who asked not to be identified.
This person also said that even if Vij actually received the inoculation, it is unlikely to offer protection unless he receives the required booster dose and a two week interval after that.
The vaccine manufacturer Bharat Biotech reiterated the same in a statement.
Experts said that you are more likely to have contracted the infection naturally from coming into contact with a positive person. “First, we don’t know if he got the vaccine or the placebo dose. Second, he did not receive both doses of the vaccine, after which the body produces an immune response. Third, no vaccine is 100% effective, ”said Dr. Puneet Mishra, a professor of community medicine and one of the vaccine researchers at the Indian Institute of Medical Sciences in New Delhi.
“Infections are likely to be reported in both the vaccine and placebo arms of one trial. Neither vaccine is 100% effective and the difference in the incidence of infection in both arms tells us the efficacy of the vaccine. Even the Moderna and Pfizer vaccines are about 95% effective. There are predefined protocols to clarify an assay. One is if there is a serious adverse event and researchers need to see if it is caused by the candidate vaccine. Even then it is done under the guidance of the data security monitoring board. Two, it is not blinded to interim analysis when there have been a certain pre-defined number of infections, ”said Dr Chandrakant Lahariya, a Delhi-based vaccinologist and public health specialist.
