Corona Vaccine: FDA gives approval to Moderna and Johnson&Johnson booster dose

New Delhi: Scientists have made another major breakthrough in the field of vaccination. In fact, the US Food and Drug Administration (FDA) on Wednesday approved booster doses of Moderna Inc. and Johnson and Johnson's corona vaccine. According to the FDA, this booster dose has to be taken as the third dose. In addition, the FDA has also approved mix-and-match booster doses. This booster dose can be given after the first dose of any vaccine.

Antibody level found to be 76 times in mix and match test

Experts said that during the mix and match trial, people who had taken Johnson & Johnson's single-dose vaccine and were given Moderna's vaccine as a booster dose, the level of antibodies in the body of such people within 15 days. increased by 76 times. Whereas in those who took Johnson & Johnson as a booster dose, the antibodies increased only four times.

WHO raised questions

Although the World Health Organization (WHO) says that even though the results of mix-and-match vaccination appear promising, more studies are needed to test its effectiveness for large-scale implementation.

Moderna's Vaccine Based on Messenger RNA

Moderna's vaccines are based on messenger RNA, while Johnson's and Johnson's vaccines use viral vector technology, according to the study. At the same time, after this claim, now officials of the US Food and Drug Administration Department will discuss the merits of the booster shot of Moderna and Johnson & Johnson vaccines later this week.

Meanwhile, India completed 100 crore vaccination so far. NITI Aayog Member (Health) Dr VK Paul said that congratulations to the people and health workers of India. Reaching the 1 billion dose mark is remarkable for any nation, a feat in just 9 months since the vaccination program was launched in India.

Given the challenges of large-scale vaccine production and distribution in the era of the unknown and unpredictable pandemic of coronavirus - the government's delivery of one billion vaccine doses is considered a major achievement. So far, China is the only country where more than 100 crore vaccine doses have been given. There in June the mark of 1 billion doses was crossed.

China is also a country with a population of over one billion. Over 2.5 crore doses were administered in a day across the country on the 71st birthday of Prime Minister Narendra Modi last month; This was the fourth time that more than one crore doses were given in a day.
