Can we reach herd immunity against COVID-19 through natural infections?
COVID-19Common questionSee full answerCan we reach herd immunity against COVID-19 through natural infections?Attempts to reach ‘herd immunity’ through exposing people to a virus are scientifically problematic and unethical. Letting COVID-19 spread through populations, of any age or health status will lead to unnecessary infections, suffering and death.The vast majority of people in most countries remain susceptible to this virus. Seroprevalence surveys suggest that in most countries, less than 10% of the population have been infected with COVID-19.We are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people. There have also been reports of people infected with COVID-19 for a second time.31 Dec 2020

This can happen either because these people got vaccinated or had already been infected. Herd immunity makes it harder for a virus to spread.So even those who haven’t been sick or vaccinated have some protection.
Can you mix and match the vaccines for your mRNA (Pfizer or Moderna) primary vaccination series?

Can the coronavirus survive on surfaces?
COVID-19Common questionCan the coronavirus survive on surfaces?It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.Mar 3, 2020
