Vaccines Are Safe
A new Food and Drug Administration review of 20 years of data collected on 57 vaccines approved during that time found that after hundreds of millions of doses, only one vaccine was withdrawn from the market for safety reasons.
There were 58 modifications to use, however, mostly involving people whose immune systems were compromised, pre-term babies and people with allergies.
New research shows that visits to emergency departments by patients with respiratory problems increase the day before thunderstorms.
Previous research had suggested thunderstorms cause pollen grains to erupt when wet, exacerbating the situation for those with asthma or allergies. The new study, though, finds that ED visits peak a day before thunderstorms hit. The reason may be changes in temperature and other fine particles in the atmosphere.
As severe weather becomes more common, hospitals are gearing up to see more affected patients.
