Developing new mRNA vaccines to fight bird flu in U.S.dairy cows.
Reading
Scientists are making new vaccines for bird flu, similar to the COVID-19 shots. They are testing these vaccines in animals and people to stop the spread of the virus.
The bird flu virus is spreading among animals like birds and cows. A few people who worked with sick cows got sick with bird flu, but they did not get very ill.
Scientists are worried that the virus could change and become more dangerous to people. They are working on vaccines to protect people in case the virus spreads easily from person to person.
Making vaccines usually takes a long time because they use chicken eggs. The new vaccines can be made faster using a different method called mRNA technology.
Scientists are testing a new vaccine for cows to see if it protects them from bird flu. They hope that vaccinating cows will also protect people who work with them from getting sick.
