In a presentation to the advisory panel Tuesday, CDC officials said that people ages 18 and older who are not immunocompromised should get the two doses of Novavax's vaccine three to eight weeks apart. Those who are immunocompromised should receive two doses three weeks apart.
First and second COVID-19 vaccine booster doses conferred substantial protection against emergency department/urgent care (ED/UC) visits and hospitalizations caused by infections with the Omicron subvariants BA.1, BA.2, and BA.2.12.1, finds a study of adults in 10 US states published late last week in Morbidity and ...
Protein subunit vaccines contain harmless and purified pieces (proteins) of the virus, which have been specifically selected for their ability to trigger immunity. Protein subunit vaccines are already used for other diseases. An example of an existing protein subunit vaccine is the one for hepatitis B.
COVID-19 vaccines are highly effective at preventing severe illness, hospitalizations, and death. Getting vaccinated is the best way to slow the spread of SARS-CoV-2, the virus that causes COVID-19.
Currently, the highly contagious BA.4 and BA.5 omicron subvariants account for most reported cases this summer. Those subvariants have caused more upper respiratory, cold and flu-like symptoms, according to Chicago's top doctor, including fever, night sweats and sore throat.
(CNN) Omicron subvariants BA. 4 and BA. 5 appear to escape antibody responses among both people who had previous Covid-19 infection and those who have been fully vaccinated and boosted, according to new data from researchers at Beth Israel Deaconess Medical Center, of Harvard Medical School.
The Novavax vaccine uses a telltale piece of the coronavirus: the notorious spike protein. All alone, the spike protein is harmless and can't cause COVID-19. When your immune system encounters the lonely spike protein, it produces antibodies against it. This gives you protection against future COVID-19 infection.
SARS-CoV-2 vaccine (mRNA-LNP, spike protein) is used as an active immunization against COVID-19 caused by the SARS-CoV-2 virus in patients 5 years of age and older.
Called Novavax, it's a more traditional vaccine that uses moth cells and tree bark. Instead of an mRNA vaccine (Pfizer, Moderna) or a viral vector vaccine (Johnson & Johnson), Novavax is a subunit protein vaccine.
Scientists are monitoring how long COVID-19 vaccine protection lasts. COVID-19 vaccines work well to prevent severe illness, hospitalization, and death. However, public health experts are seeing decreases in the protection COVID-19 vaccines provide over time, especially for certain groups of people.
Getting vaccinated yourself may also protect people around you, particularly people at increased risk for severe illness from COVID-19. Getting sick with COVID-19 can cause severe illness or death, and we can't reliably predict who will have mild or severe illness. If you get sick, you can spread COVID-19 to others
Some fully vaccinated people will still get COVID-19 if they are exposed to the virus that causes COVID-19. These are called vaccine breakthrough infections. People with vaccine breakthrough infections may spread COVID-19 to others.
Our findings indicate that vaccine effectiveness against symptomatic disease caused by the omicron variant is substantially lower than with the delta variant. After two doses, vaccine effectiveness waned rapidly, with very limited vaccine effects seen from 20 weeks after the second dose of any vaccine.
The most recent research from the CDC suggests that protection from the Pfizer and Moderna COVID-19 vaccines starts to fade around 4 months after a booster dose.

Their symptoms are generally flu-like and similar to those of previous variants. But in many cases, the headache, fever and coughing are milder. The loss of taste and smell may also be much less prevalent with omicron than it was with delta.
