When can I return to normal life after being vaccinated?
Even if countries authorize a vaccine, they can vaccinate a few percent of their citizens at first. The unvaccinated people still remain vulnerable. A growing number of vaccines show robust protection against becoming sick but scientists do not know yet if they block the transmission of the coronavirus. So for the time being, even vaccinated people will need to wear masks and avoid indoor crowd. Experts’ projections differ but most expect fall 2021 is when life will return to something like normal.
If I’ve been vaccinated, do I still take precautions?
Yes. Vaccines clearly protect people from getting sick but we do not know yet if vaccinated people could still spread the virus without developing symptoms. We know that people who are naturally infected can spread it while experiencing no symptoms. Until scientists can be sure, even vaccinated people will need to take safety precautions including wearing masks and keeping safe distance.
What are the side effects of coronavirus vaccines?
The Pfizer and BioNTech vaccine is delivered as a shot in the arm. Tens of thousands of people have already received the vaccines and none have reported any serious problems. Some experienced short-lived discomfort, including aches and flu-like symptoms that typically last a day. The experiences are the sign that your body’s immune system is mounting a potent response that will provide long-lasting immunity.
Will mRNA vaccines change my genes?
No. The vaccines from Moderan and Pfizer uses a genetic molecule, known as mRNA to prime the immune system. Once primed, body’s immune system will eventually destroy it. The cell uses the mRNA to make proteins from the coronavirus, which can stimulate the immune system. Once those proteins are made, our cells shred the mRNA with special enzymes. The mRNA can only last for a few days at most.
