Table 1. Antiviral Medications Recommended for Treatment and Chemoprophylaxis of Influenza
| Antiviral Agent | Activity Against | Use |
|---|---|---|
| Oral Oseltamivir | Influenza A and B | Chemo- prophylaxis |
| Inhaled Zanamivir | Influenza A and B | Treatment |
| Chemo- prophylaxis | ||
| Intravenous Peramivir | Influenza A and B4 | Treatment |
What type of vaccine is used for influenza?
Two types of influenza vaccine are widely available: inactivated influenza vaccines (IIV) and live attenuated influenza vaccines (LAIV). Traditionally, influenza vaccines (both IIV and LAIV) have been produced to protect against 3 different seasonal influenza viruses (also called trivalent vaccines).
Are flu vaccines prophylactic?
Prevention of infection is most effectively accomplished by vaccination. Vaccination with the inactivated, intramuscular influenza vaccine has been clearly demonstrated to reduce serious morbidity and mortality associated with influenza infection, especially in groups of patients at high risk (e.g. the elderly).
Is there an influenza C vaccine?
There is no vaccine against influenza C virus.
Who needs influenza prophylaxis?
Prophylaxis should be provided (1) to high-risk children who have not yet received immunization and during the 2 weeks after immunization, (2) to unimmunized family members and health care professionals with close contact with high-risk unimmunized children or infants who are younger than 6 months, and (3) for control …
When is prophylactic oseltamivir recommended?
Oseltamivir is also useful for influenza prophylaxis within 48 hours of contact with an infected individual in adults and children greater than one year of age.
What type of vaccine is Johnson and Johnson?
The Moderna and Pfizer vaccines use mRNA technology, and the Johnson & Johnson vaccine uses the more traditional virus-based technology. mRNA is essentially a little piece of code that the vaccine delivers to your cells.
Who should get prophylaxis for influenza?
How do scientists distinguish between subtypes of the flu?
Influenza A viruses are classified by subtypes based on the properties of their hemagglutinin (H or HA) and neuraminidase (N or NA) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers – e.g., A(H1N1), A(H3N2).
