Coronaviruses range from the common cold to more severe infections such as SARS (SARS-CoV) and MERS (MERS-CoV) and the current Covid-19 (SARS-CoV-2). As yet there is no FDA-approved vaccine to prevent coronavirus infections. These both have FDA emergency use authorization. AFP / DOMINICK REUTER Two of the Covid-19 vaccines available in the US use messenger RNA technology to prevent or reduce the symptoms of Covid-19 infection.   This mRNA vaccine technology is new; the consequences of altered DNA, if any, are unknown. However,  others,  including the  CDC  said that the vaccine would not interact with DNA. Other scientists believe that mRNA vaccines can enter and permanently alter DNA.  Like DNA vaccines, RNA vaccines use part of the genetic code of the virus to get the immune system to respond.  An  article  currently in preprint (not yet peer reviewed) discusses a lab study in which some pieces of Covid-19 RNA were converted to DNA and then integrated into human chromosomes.   Medica

As of January 2021, there are more than 4,300 studies that have been launched to investigate various treatments for COVID-19. You can review the details of these trials on  ClinicalTrials.gov . New ones are being added every day.  Below, we look at the top 10 most tested categories. 1. Vaccine This is the most watched and anticipated category. Technically, vaccine is not considered a treatment but rather a preventive strategy to boost your immune system and reduce the risk of getting COVID-19. As of January 2021, researchers are currently testing  67 vaccines  in clinical trials on humans, and 20 have reached the final stages of testing. The vaccine remains a promising agent for COVID-19 protection, and the published reports of the candidate vaccines showcase some encouraging results. Major vaccine candidates: Pfizer/BioNTech COVID-19 mRNA vaccine - This is the first vaccine to receive WHO validation for emergency use. Oxford - AstraZeneca (inactivated vaccine) Moderna (mRNA vaccine) S
