July 31, 2023 Allergy/Immunology Scientists discover antibodies capable of stopping several coronaviruses, potentially preventing future outbreaks
May 4, 2022 Allergy/Immunology Small in vitro study suggests two new COVID subvariants may dodge natural immunity response. However whether this translates into worsening clinical outcomes remains unanswered.
September 14, 2021 Allergy/Immunology We are not seeing ‘waning immunity’ in fully vaccinated people to date. Some require the 3rd dose specific medical or medication reasons. The intricacies of our immune system are astounding and fascinating. #vaccineswork
September 1, 2021 Health Headlines Moderna vs Pfizer antibody titre study cannot answer if it leads to differences in cellular immunity, protection against variants, duration, risks of transmission or clinical outcomes. Real world data shows they both work equally well. #vaccineswork
June 4, 2021 Allergy/Immunology Pfizer vaccine recipients have lower neutralizing antibodies targeting delta variant up to three months after first dose. Outcome data needed to determine if this translates into less efficacy. Study concludes second dose interval needs to be shortened.
December 24, 2020 Allergy/Immunology NEJM study concludes that time required to determine Moderna’s effect on longevity of antibody, B and T cell response. However, the vaccine works. Worst-case scenario is that we will require a booster.
October 30, 2020 Allergy/Immunology Study reports that people who had mild to moderate #COVID-19 have protective stable antibody levels five months after their infection. This finding and further studies to follow can help with public policy and vaccine development programs.
October 29, 2020 Allergy/Immunology Vulnerable populations to be the focus in a new Canadian COVID-19 antibody study.
October 14, 2020 Allergy/Immunology It is too soon to draw any conclusions about short/long term immunity based on COVID-19 antibody levels. Many unknown factors remain. Time should help with the answers in future studies.
July 16, 2020 Allergy/Immunology Still too early in the pandemic to determine how long immunity lasts after initial infection.
