In the United States, the vaccine is authorized as two doses taken 21 days apart. To protect against Covid-19, the first dose primes the immune system and the second boosts it.Covid-19 antibodies may protect against reinfection later, study suggestsOne of those new papers, led by researchers at the University College London and Public Health England, included data on 51 health care workers in London. Among those workers, 24 previously had Covid-19.
How antibodies protect us from viruses 01:37The other paper, from researchers at Imperial College London and other institutions in the United Kingdom, included data on 72 health care workers who were vaccinated in late December. Twenty-one of them had evidence of previous coronavirus infection. Read MoreThe workers provided blood samples at the time of receiving their first dose and then 21 to 25 days after vaccination.
Dr. Fauci: Why you need two vaccine doses 02:26Offit added,"If you've never been infected with this virus before, that second dose of mRNA vaccine dramatically boosts your T-cell immunity, dramatically boosts your antibody response, and will no doubt give more complete and longer-lived protection."It's possible a single dose of coronavirus vaccine might be enough to protect people who have recovered from a bout of Covid-19, Dr.
"Are those people who are in between first and second actually sitting ducks for getting infected?" Collins asked."Is that actually a way that we might encourage more mutations to happen because they're only partly protected? The virus has a chance to live a little longer in their system and pick up some changes." Collins said that until the data show otherwise, the authorized two doses three to four weeks apart is the regimen that should be followed.
like saying pfizer knows nature better than nature itself.

😂I have a problem with the Lancet and COVID-19, since they made hydroxychloroquine the drug of the drugs to treat Covid.
Reading between the lines, then... having survived covid does not give you immunity, and the vaccine alone may not either?
At this point, I want to get sick and die,don't ask why
I’m not a lab rat
You likely already have a strong enough immune response to Covid if you had Covid already. Geeze. How idiotic is this conclusion. Do they know if they’re measuring vaccine response or innate immune response?
itz No vaccine u idotz..itz a medicine 4 a desease u do not have,,fkin morons
Good news if this is true
These comments are frustrating. Nobody is ever happy.
Vaccines are not important. Getting viruses and our appetite for cheap products made in China by quasi-slaves go together. If China does not reinvent communism soon, we will all wish to die quickly into the hands of some viruses. With its dumping, China will steal all your jobs.
This is Great news and promising. The more people get the COVID19Vaccine the better for all. With more immune boosters life will get better for many and HeadingBacktoNormal soon
So open the schools.
This scientifically doesn't make any sense
jesus is coming
