The company's investigational vaccine, which is in a phase 3 study, is an example of its commitment to addressing these viruses.

At 1 year after COVID-19 infection, children’s neutralizing antibodies only differed by vaccination status.

Despite a significantly slower than expected COVID-19 vaccine rollout, Novavax reports early 2022 as its first profitable quarter.

The higher the gestational age when pregnant women received a COVID-19 vaccine, the higher the serological titers at birth.

Active immunization of pregnant women with investigational vaccine protected infants from RSV from birth through at least 6 months.

Children living with HIV had a similar immune response to mRNA COVID-19 vaccination as children without HIV.

A member of the herpes family, Epstein-Barr virus is the primary cause of infectious mononucleosis and may also cause certain cancers and autoimmune diseases.

A recent study examined whether immune response to the Pfizer-BioNTech COVID-19 vaccine differed by age and gender.

The filing included data from their phase 2/3 trial in this pediatric age group.

A shorter dosing period and no extra risk of suffering acute myocardial infarction means the newer 2-dose hepatitis B vaccine is an attractive option for protection.

An ECCMID study found COVID-19 primary infections were more severe than reinfections, and vaccination further reduced symptoms.

One study, presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), found waiting longer in between the first and second Pfizer-BioNTech vaccine doses boosted immune response 9-fold.
