Recently, many positive news of economic recovery has given everyone hope. However, it may remain to be seen whether the current COVID vaccine will be able to eradicate the growing outbreak or not.
health officials in Canada‘s B.C. province announced Monday an outbreak of COVID-19 at Cottonwoods Care Centre in Kelowna, where residents have been vaccinated against the Chinese Communist virus.
At a news conference, B.C. health officer Dr. Bonnie Henry said vaccination does not mean it will stop the spread of the virus and that precautions taken for seniors and care homes still need to be maintained.
She said, “Even if people are fully vaccinated, the virus can still be spread. However, the symptoms caused by the virus will lessen, it won’t spread as much, and we won’t see an explosive outbreak.”
Currently, two staff members and 10 residents at Cottonwoods Care Center have been diagnosed. The care center has a total of 221 publicly funded care beds, and Dr. Henry said all staff and residents have been vaccinated and some of the confirmed cases have received a second dose of the vaccine.
“This reminds us that while we believe the vaccine is very effective in preventing serious illness and death, it doesn’t necessarily mean that all transmission will stop.”
In fact, back in February, U.S. media outlet CNN reported that some people were diagnosed with the new crown even after receiving the vaccine.
For example, Democratic Congressman Stephen Lynch of Massachusetts tested positive for COVID-19 after receiving his second dose of the Pfizer vaccine, and basketball coach Rick Pitino was diagnosed with the CCP virus after receiving his first dose of the vaccine.
So, what is the cause?
According to the CDC, it takes days, if not weeks, for the vaccine to take effect. Perhaps, you were positive before the vaccine was administered.
“It takes a while for an immune response to develop,” says Dr. Robert Salata, head of the Roe Green Center for Travel Medicine and Global Health at University Hospitals in Cleveland.
The first dose of the vaccine may offer some protection, but as Modena CEO Stephane Bance says, “We really don’t have any data to prove that right now.”
For the Pfizer vaccine, Dr. Salata, who led the study of the vaccine at his hospital, said that after 14 days of vaccination, the first dose was only 52 percent effective in preventing the disease. Clinical trial results for the Pfizer vaccine showed a 95 percent disease prevention effectiveness rate after two doses.
The Modena vaccine, on the other hand, was 94 percent effective after two doses, not 100 percent.
Moreover, the CCLV vaccine does prevent disease, but it is not clear whether it prevents infection.
Dr. William Schaffner, an infectious disease specialist and professor of preventive medicine in the Department of Health Policy at Vanderbilt University, said, “Information on whether the vaccine stops infection and whether it keeps infected people asymptomatic is still not clear.”
Namandje Bumpus, chair of the Department of Pharmacology and Molecular Sciences at Johns Hopkins University, said, “As far as we can see, these vaccines have really changed the course of the Epidemic in terms of preventing disease and controlling the severity of the disease.”
“But focusing on the efficiency numbers doesn’t tell the whole story, because you can still get a new crown. But by all indications, the disease in these confirmed cases is really not as severe as in unvaccinated patients, and that does matter.”
Vaccine manufacturers are still working on whether the vaccine just saves people from serious illnesses or if it provides complete protection from infection.
It is still possible to test positive for COVID-19 if you have no symptoms. Such patients are called asymptomatic virus carriers. This also means that even if you are vaccinated, you can still transmit COVID-19. this is why you need to wear a mask even if you are vaccinated.
In addition, according to studies released by the CDC, there are some people who have been infected before they receive their first vaccination.
