Antibodies...

 

The UK’s decision to delay second doses of coronavirus vaccines has received fresh support from research on the over-80s which found that giving the Pfizer/BioNTech booster after 12 weeks rather than three produced a much stronger antibody response.

A study led by the University of Birmingham in collaboration with Public Health England found that antibodies against the virus were three-and-a-half times higher in those who had the second shot after 12 weeks compared with those who had it after a three-week interval.

Dr Helen Parry, a senior author on the study at Birmingham, said: “We’ve shown that peak antibody responses after the second Pfizer vaccination are really strongly boosted in older people when this is delayed to 11 to 12 weeks. There is a marked difference between these two schedules in terms of antibody responses we see.”

With these major differences, the rush that we are having in USA to just jab the vaccines in any body at short interval is not the best.

Let us take a second look at the current rush and make a scientific decision regarding when, who and what. Just a thought.
