I am now in the habit of regularly reading Dr. Francis Collins’ blog at https://directorsblog.nih.gov/. Most of the latest information about potential vaccines, clinical trials, and COVID-19 therapies can be found here before they reach mainstream media. Dr. Collins (author of The Language of God) is a brilliant scientific mind, the director of the National Institute of Health, and a humble follower of Jesus Christ. His latest blog gives us more great news about potential therapies for COVID-19. You can read the blog yourself (as it is not overly technical) and I will also provide a summary here.
The good news is there in the first paragraph: we now know that nearly everyone who recovers from COVID-19 produces antibodies against SARS-CoV-2. This is the virus that causes the respiratory disease COVID-19. This suggests that, at least for a period of time – perhaps six months to several years, people exposed to SARS-CoV-2 will be protected from getting COVID-19 again. It is also quite possible that this protection, or immunity, could be transferred to other individuals who have not yet been exposed to the virus. Canadian Blood Services may already be storing tubes of blood for testing to see who has these antibodies in their blood. Such blood samples would be valuable in identifying plasma that could be transferred to others to effectively block the replication of the virus in the cells of those exposed to the virus. As Collins' blog also suggests, the antibodies in this plasma may also be an effective therapy for those in an active COVID-19 disease state.
The article goes into some technical details about the various forms which these antibodies take and gives credit to those involved in this important work. The researchers come from all over the world including Beijing, Europe, and the United States. It is a good example of a unified research and development process. I really appreciate good news about actual potential therapies rather than speculation on drugs that may or may not work against the virus. I also really appreciate that these scientists put aside political quarrelling for the sake of all humanity. I encourage us all to stay informed, continue to use our intellects, and stay positive in the search for a conclusion to this pandemic.
