WASHINGTON: A recent study has quashed rumours that Covid-19 vaccination leads to infertility. The study published in the 'American Journal of Epidemiology' asserts that Covid-19 vaccination does not appear to affect fertility. The prospective study of couples trying to conceive found no association between Covid-19 vaccination and fecundability -- the probability of conception per menstrual cycle -- in female or male partners who received the Pfizer-BioNTech, Moderna, or Johnson & Johnson vaccines. In contrast, the findings indicated that Covid-19 infection among males may temporarily reduce fertility -- an outcome that could be avoidable through vaccination. "Many reproductive-aged individuals have cited concerns about fertility as a reason for remaining unvaccinated," said study lead author Dr Amelia Wesselink, research assistant professor of epidemiology at BUSPH. "Our study shows for the first time that Covid-19 vaccination in either partner is unrel...

Moderna vaccine ‘highly effective' against coronavirus variants: Study

LOS ANGELES: Two doses of Moderna Covid-19 vaccine are highly effective against SARS-CoV-2 variants, but protection against Delta infection decreases over time, according to a study conducted in the US. At the time of the study, the omicron variant had not yet been detected in the Southern California region, the researchers said. The research, published in The British Medical Journal on Wednesday, showed the vaccine was effective against Covid-19 hospitalisation associated with the Delta variant. However, vaccine effectiveness against the variant moderately declined with increasing time after vaccination. "This study confirmed effectiveness against all variants during the study period, although we did find a drop in effectiveness over time against Delta infection, from 94 per cent effectiveness in the first 2 months after vaccination to 80 per cent effectiveness after 6 months," said Katia Bruxvoort, from Kaiser Permanente, US. "Protection against hospitalisation due...
