What happens if you take the second COVID-19 vaccine?
When you take two doses of a COVID-19 vaccine, the first dose is the first time for your body to see the spike protein that the COVID-19 vaccines produce, and your body begins to develop an immune response. But that happens slowly. Then when you come back with a second dose, your body is ready to attack it. Mar 24, 2021
When do you get the second COVID-19 vaccine?

Are there face masks that should not be worn during the COVID-19 pandemic?
See full answer Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. A face covering without vents or holes will also filter out particles containing the virus from inhaled and exhaled air, reducing the chances of infection. But, if the mask include an exhalation valve, a wearer that is infected (maybe without having noticed that, and asymptomatic) would transmit the virus outwards through it, despite any certification they can have.So the masks with exhalation valve are not for the infected wearers, and are not reliable to stop the pandemic in a large scale. Many countries and local jurisdictions encourage or mandate the use of face masks or cloth face coverings by members of the public to limit the spread of the virus.
Does wearing a mask harm your health?
No, wearing a mask will not harm your health even if you are sick with a cold or allergies. If your mask gets too moist just make sure you are changing it regularly. Jul 2, 2020
Why don’t you get sick after the COVID-19 vaccine?
But you don’t actually get sick because your body is only exposed to a small portion of the virus and not the intact virus that can cause the disease. The antibodies against the spike protein remain in your body and are available and ready to protect you if you’re exposed to the SARS-CoV-2 virus. May 18, 2021
What exactly does the COVID-19 vaccine do to the body?
COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without us having to get the illness.
How long does it take for immunity to start after receiving the Pfizer COVID-19 vaccine?
Data released by the U.S. Food and Drug Administration (FDA) show that COVID-19 protection from the Pfizer/BioNTech vaccine was demonstrated in the clinical trials at about 14 days after the first shot. The FDA said some level of immunity may start sooner, but how much is not certain.
How many people in America need to be vaccinated against COVID-19 to achieve herd immunity?
Although figures vary, scientists estimate that between 70% and 85% of Americans will need to be vaccinated against the coronavirus to achieve herd immunity. Feb 12, 2021
What is herd immunity in the context of COVID-19?
Put simply, herd immunity means a large portion of a community is immune to a disease, making further disease spread unlikely. Immunity is conferred either by building antibodies after an infection from the virus or from a vaccine. May 21, 2021
