Do declining antibodies to SARS-CoV-2 mean long-lasting immunity is impossible? What do mutations in the virus mean for vaccine effectiveness? Can we use sewage water to monitor the pandemic? On this episode of Beyond the Abstract, Derek and Ellen talk about three recent papers related to these important COVID-19 issues.Note: Since recording this episode, there have been more documented cases of severe allergic reactions to the vaccine. However, the number of cases relative to the number of vaccinations is still extremely low indicating the vaccine is generally safe. Currently, it is thought that polyethylene glycol (a chemical ingredient in the vaccine) is the culprit behind the reactions, but this has not been confirmed. You can read more about this in Science and on the CDC Website. Please consult your physician if you have concerns about getting the vaccine.On January 10th, the day prior to publication of this episode, COVID-19 cases in the US crossed 22 million with over 200,000 new cases that day.Ward et al.
