Pfizer says third dose of vaccine is "probably" necessary

Pfizer says third dose of vaccine is "probably" necessary

As of yet, it is unknown for how long Pfizer vaccines protect against COVID-19, given the short-lived path of this product.
The CEO of the pharmaceutical company Pfizer, Albert Bourla, assured that a third booster dose of the COVID-19 vaccine is "probably" necessary within 12 months after being fully vaccinated, for the immunization to be complete.

"It is extremely important to suppress the group of people who may be susceptible to the virus," Bourla told CNBC television in a statement released Thursday.

The executive also indicated that these doses will be an important tool to fight against the variants of COVID-19 that have proven to be more contagious (and making the pharmaceutical companies, again, richer and richer).

So far, it is unknown for how long vaccines protect against COVID-19, given the short haul of this product.

Pfizer recently reported that its COVID-19 vaccine was more than 91% effective against the virus and more than 95% effective against severe symptoms of the disease and that this protection was maintained for at least six months after receiving the first dose.

Likewise, people who receive Moderna's COVID-19 vaccine, which is similar in composition to Pfizer's, continue to show high levels of antibodies six months after the second dose, according to a study published in the scientific journal The New England Journal of Medicine. earlier this month.

The study released by Pfizer showed that its vaccine appears to work similarly against the majority variant of the virus in South Africa, one of the countries where the product was tested.

Pharmaceutical Pfizer announced on February 26 that it would study the possibility of injecting a third dose to vaccinated people to try to strengthen protection against the most aggressive variants of the coronavirus.

Bourla said then that with this third dose the antibody response could be strengthened between 10 and 20 times and stressed that just as people are vaccinated annually against the flu, they will have to do it against covid-19 to be protected.

This new study is aimed at two age groups, people between 65 and 85 years and those between 18 and 55 and will be chosen from the group that already participated in the first trials carried out by the pharmaceutical company Pfizer in cooperation with BioNTech.

The University of Oxford has started a new clinical study to determine if doses of the vaccines can be combined and obtain an adequate immune response with two doses regardless of the manufacturer.

The researchers already have the participation of the vaccine from AstraZeneca, Pfizer, Moderna and the American candidate Novavax.

Mhogan you could see the benefit if you were looking at the drug companies bank statement. And it also puts stupid peoples mind at ease, well until the wheels come off the wagon down the road.

No protection is right. Worse is that new data out of CDC has 5,800 fully vaccinated people becoming infected with over 400 hospitalizations and 74 Covid deaths. Panama brags about a 1.7% case fatality rate—well 5,800 with 74 deaths is 1.3% fatality rate of Covid-fully vaccinated-cases. And it’s only been less than 4 months and DOES NOT INCLUDE vaccine caused deaths. Hard to see any benefit!

So - this vaccine is no protection!
