Posted: Updated:

Reports about Ebola may not appear in the media much any more but researchers have been working hard on a vaccine for the deadly virus It now appears those efforts are paying off.

The National Institute Of Allergy and Infectious Disease reports two experimental Ebola vaccines are safe. They were also shown to be protective for at least a year after vaccination.

The studies are based on 1,500 adults involved in the study during the West Africa Ebola outbreak. 

Few cases of Zika

Another virus, Zika, caused tremendous concern for Olympic athletes traveling to Rio de Janeiro last summer. But a new study of 457 U.S. athletes and staff, found none became infected while in Brazil. 

Blood tests showed about 7 percent did get West Nile virus, Dengue or Chikungunya. Only a few had mild illnesses and most never even knew they were infected.
