Delay in second dose of corona vaccine is better, new research

Toronto: A new study from Canada has found that a second dose of MRNA vaccine, three to four weeks after the recommended duration, is better for preventing Covid 19.

This is because during this extra period, the body’s immunity against the coronavirus (after taking the first dose) gradually increases. This is followed by a second dose that strengthens the immune system.

The study was funded by the Canadian government’s “Cowd 19 Immunity Task Force” (CITF), led by Dr. Brian Grunau, an assistant professor at the University of British Columbia.
It should be noted that there are currently two MRNA vaccines available for Covid 19, one developed by Pfizer / BioNTech and the other by Moderna.

The full course of both vaccines consists of two doses. According to the US Agency for International Development (CDC), the second dose should be given 21 days after the first dose of the Pfizer vaccine, and 28 days after the first dose of the modern vaccine.

In contrast, a study published in the latest issue of the Oxford Academic Research Journal “Clinical Infectious Diseases” by Canadian experts states that the second dose is 42 to 49 days (6 to 7 weeks) after the first dose of both vaccines. (Second dose) is more effective.

The study was performed on 186 members of the medical staff, two-thirds of whom were infected with Pfizer, while the other one-third were vaccinated with the modern MRNA vaccine.

They administered a second dose of the vaccine 42 to 49 days later instead of the recommended interval (21 and 28 days).

A few days after the vaccination was completed, when blood samples were taken from all of these individuals and analyzed, it was found that they contained more antibodies to the corona virus, compared to those who received the second dose of the vaccine after the recommended interval. I was significantly more.

High doses of antibodies against the corona virus meant that those who took the second dose late had higher resistance to Covid 19 than others.

Earlier, only one study of its kind had been conducted in the UK on the “Oxford AstraZeneca” vaccine. The study also found that a second dose a few weeks later was more beneficial than the recommended interval.

Controversial break and booster dose

In their study, Canadian experts called the recent proposed interval between the two doses of the Covid 19 vaccine “controversial” and insisted that it was more beneficial to keep the interval between 42 and 49 days as it would be appropriate for the body’s immune system during this period. It takes time for them to strengthen themselves against this virus and disease.

According to the CDC, booster doses should be given at least six months after full vaccination against the corona virus. But this study suggests that if the interval between the first and second doses is increased, the need for a booster dose will probably not remain.

However, this is a matter for research, of which only experts can say.
