People that are unvaccinated from Covid but get the virus and still beat it after wards means the rate of survival is 99.8%. People are not sure how long a vaccine can last in the human body probley 4 months maximum that’s what other think. Vaccines are made with a little bit of the virus in or salt or something and they make them and put the liquid in a little jar. This medicine is then sucked out of the jar with a syringe and given to the patient in the one arm then swapped too the other if there’s more than one dose.
Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell. This is for people that’s got Covid or any disease.
