If I already had COVID-19, do I have to get vaccinated or is it not necessary?
So far, there is no conclusive data on the immunity periods generated by having had the disease. For now, and at a global level, the vaccines are still considered to be the most effective prevention method. In any case, we recommend that before deciding, you consult your primary care physician or the specialist who monitored your health when you had the virus.
Can I be infected by the vaccine itself?
It is not possible to contract COVID-19 from COVID-19 vaccines, as these vaccines do not contain living viruses.
How many people should be vaccinated to ensure collective immunity?
It is estimated that 65% to 70% of the population will need to develop an antibody response to achieve collective immunity. However, to achieve this percentage of coverage given the efficacy of the available vaccines, a higher population of people has to be vaccinated (around 85%).
Now that the vaccine is being distributed, will other prevention measures change?
No. Preventive measures, both at work and in other spaces, must be maintained, especially the use of a mask, hand washing, sanitization of environments, social distancing, etc. On the other hand, the development of all available vaccines is so recent that it is not yet possible to ascertain how long the immunization will last in each case. We need to wait without lowering our guard, maintaining all preventative measures.
