Despite vaccine shortages, many younger people in New York City accessed vaccines ahead of schedule, particularly in high-income areas, according to new research at Columbia University Mailman School of Public Health.
Low-income areas with high proportions of older people demonstrated lower coverage rates than wealthier areas in the first three months of vaccine rollout, and higher mortality over the year. The findings are published in the Journal of Urban Health.
Antibody levels fell to low or near zero within the first few months of getting the vaccine, unless the person had previously received a smallpox vaccine, scientists reported Saturday at the European Congress of Clinical Microbiology and Infectious Diseases in Barcelona.
The mRNA-1283 vaccine showed a higher immune response—including in seniors—than its currently licensed vaccine, called mRNA-1273.222. Response was higher against Omicron BA.4/BA.5 as well as the original SARS-CoV-2 virus.
