(Reuters) -The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.
Autoimmune disease treatments may reduce vaccine responses
Immunosuppressive drugs for inflammatory diseases like rheumatoid arthritis, multiple sclerosis, and ulcerative colitis can impair the body’s response to the COVID-19 vaccines from Pfizer/BioNTech and Moderna, according to new data. In 133 fully vaccinated people with such conditions, antibody levels and virus neutralization were about three-fold lower than in a comparison group of vaccinated individuals not taking those medicine, researchers reported on Friday on medRxiv ahead of peer review.

Studies show vaccinated moms pass COVID-19 antibodies to babies through breastfeeding
Studies show vaccinated moms pass COVID-19 antibodies to babies through breastfeeding By Sara Goldenberg | April 9, 2021 at 8:57 PM EDT - Updated April 9 at 8:57 PM
CLEVELAND, Ohio (WOIO) - Promising news for new parents.
Moms may protect their babies and toddlers from COVID-19 through breastfeeding.
New research shows the vaccine can transfer antibodies from mothers to babies.
A North Carolina baby has tested positive for COVID-19 antibodies, but he didn’t get them from the virus.
Instead, he got the antibodies from breastfeeding.
“Over time we’re seeing that the more he’s been breastfeeding that he is showing more antibodies now,” said Jameson’s mom, Katy Robertson, a family nurse practitioner.

TORONTO Although the current COVID-19 vaccines have not been approved for infants, it turns out there may be another way babies can get antibodies in their system: through the breast milk of mothers who have been vaccinated themselves. Several recent studies have shown that antibodies can be passed from mothers to their infants through breastfeeding. Previous studies looked at mothers who were infected with COVID-19 themselves, but emerging data has also looked at whether vaccinated mothers may be able to pass along antibodies. One small study, published at the end of March in the American Journal of Obstetrics and Gynecology, tracked five women for a period of several months in order to measure how long antibodies might be present in breast milk after vaccination.
