Massachusetts Democratic U.S. Rep. Stephen Lynch (D) tested positive for Neocon nine days after receiving two doses of the Pfizer vaccine; similar cases show that Neocon protection is not comprehensive or immediate, for reasons that may include: the Time it takes from vaccination to protection, the fact that the vaccine is not 100% effective, the fact that the vaccine was already infected before vaccination, and the fact that the vaccine may not protect against some variants of the virus. The last of these is of particular concern.
It takes time for immunity to develop
According to the Centers for Disease Control and Prevention (CDC), it takes several days to weeks for a vaccine to develop an immune response. Vaccine recipients may become infected and develop a positive reaction before the vaccine actually works.
Robert Salata, chief of the Pfizer vaccine survey at Cleveland University Hospital, said the Pfizer vaccine is about 52 percent effective 14 days after the first dose; Stephane Bancel, CEO of Moderna Vaccine, said the first dose provides some protection, but “there is no data to prove it.
Vaccine is never 100 percent effective
The vaccine is not 100 percent effective, so it may still test positive after vaccination; both the Pfizer and Modena vaccines currently licensed in the United States are very effective, but according to clinical trials, after two doses, the Pfizer vaccine is 95 percent effective in preventing disease, and the Modena vaccine is 94 percent effective in preventing disease.
William Schaffner, a professor at Vanderbilt University Medical Center, said, “It’s unclear whether these vaccines will stop the virus from infecting and remain asymptomatic.”
Bumpus (Namandje Bumpus), chair of the Department of Pharmacology and Molecular Sciences at Johns Hopkins University, said, “Vaccines have really changed the game in terms of preventing disease and even serious illness. Vaccinated people can still get the disease, but the signs are that vaccinated people do get sick much less than unvaccinated people, and that’s important.
New crown infection before vaccination
The fact that an asymptomatic person can still test positive means that the vaccinated person can still transmit the Neoplastic virus. This is why vaccinees should still wear masks.
One of the possible reasons for a positive test after vaccination is that the person was already infected before vaccination and did not know it, according to a study released by the CDC on January 1, which found that 22 of the 4,081 health care workers who received the vaccine tested positive after the first dose. Study author Eyal Leshem, a travel Medicine specialist at Sheba Medical Center in Israel, said it was clear that some of the health care workers who tested positive had been infected with COVID “before the first dose was administered.
May not protect against variants of the virus
The concern is that the vaccine may be less likely to protect against some variants of the virus already circulating in the United States. Preliminary laboratory data suggest that the vaccine will provide protection, but public health officials want to get vaccinated as soon as possible to prevent the disease from taking advantage of the Variant virus.
Vaccine manufacturers say they are testing whether the vaccine can fight the variant virus and are also developing boosters to add additional defense against the variant virus. For a year from now, I’ll be getting the flu vaccine in one hand and the new coronavirus vaccine in the other,” Scherfner said. We have to adapt our approach to the new strain of the virus. We have the ability to keep up with the evolution of the virus and even surpass it.”
