Advice on Pfizer's COVID-19 Vaccine

So first: what is a vaccine? a vaccine teaches our immune system how to create antibodies, and it is these antibodies that protect people from disease. It is much safer for our immune system and our overall health, to make antibodies through vaccination than by actually catching the virus from someone else, because then your immune system has to mobilise and produce large quantities of antibodies to fight the virus. Once our immune system knows how to fight a disease, this offers protection against this disease for many years.

So in Ireland in the new year, a COVID 19 vaccine which has been developed by Pfizer and German biotech company Bio N Tech will be distributed by the HSE through GP’s, pharmacies and health centres.
