Pfizer scientists say it’s not enough to work at prevention through vaccination. It's also important to be able to tackle the virus once it gains a foothold in the human body. That’s where the new anti-virus pill comes into play.
Pfizer says the level of administration of the vaccine so far shows it is working and it is safe. The vaccine which was jointly developed with European partner firm BioNTech continues to be produced and shipped from the Pfizer pharmaceutical plant in Portage.
