COVID-19 Vaccine in Israel & Effectiveness for Variants
From BBC (1/25/21): Moderna vaccine appears to work against variants
An excerpt:
“For the Moderna study, researchers looked at blood samples taken from eight people who had received the recommended two doses of the Moderna vaccine. The findings are yet to be peer reviewed, but suggest immunity from the vaccine recognises the new variants. Neutralising antibodies, made by the body’s immune system, stop the virus from entering cells.
Blood samples exposed to the new variants appeared to have sufficient antibodies to achieve this neutralising effect, although it was not as strong for the South Africa variant as for the UK one. Moderna says this could mean that protection against the South Africa variant might disappear more quickly.”
More on COVID-19 Vaccines
Yesterday, Evan Anderson (infectious disease) shared some updates on COVID-19 vaccines.
- Dr. Anderson noted that more research is needed in children, pregnant women and immunocompromised populations. Immunocompromised patients may have a lower response rate to vaccination.
- The South African 501Y.V2 COVID-19 variant may be less responsive to neutralization from donor plasma and the vaccines may be less effective in this variant.
- He reviewed ACIP recommendations -available from CDC website as well
- Dr. Anderson noted there is a good response to vaccination even in those with a lack of adverse effects with vaccination
- Immunity after vaccination: data has been published showing good antibody levels at 3 months. Moderna has stated that they expect vaccine will provide immunity for at least a year
- Immunity after infection with COVID-19: at least 3 months. Those with milder infection are more likely to get reinfected.
- Antibody testing after vaccination to assess for immunity is not recommended
Vaccination Recommendations for IBD Patients
Siegel CA, Melmed GY, McGovern DP, et al. Full text link: SARS-CoV-2 vaccination for patients with inflammatory bowel diseases: recommendations from an international consensus meeting Gut Published Online First: 20 January 2021. doi: 10.1136/gutjnl-2020-324000
In the article, they note “the exception is for any live-attenuated virus vaccines or replication-competent viral vector vaccines that come to market.” Currently, all of the vaccines are inactivated (not live-attenuated).
These recommendations apply to approved populations which currently do not include pediatric patients or patients who are pregnant.

“A doctor researched the safety of the COVID-19 vaccinations not only to counsel his patients and staff but also to make his own decision about whether to get the vaccine.
Carey Goldberg of WBUR has the story about how most of the staff at the Cambridge Health Alliance COVID-19 clinic in Somerville, Massachusetts, “got to yes.”
