Influenza
Influenza ( 16 Questions)
Avoiding vaccination and relying on natural immunity is not the best approach to prevent influenza. Natural immunity may not provide adequate protection against the constantly changing influenza virus, and the risk of severe illness and complications is higher without vaccination.
Washing hands frequently and using alcohol-based hand sanitizer are effective preventive measures for various infections, including the flu. However, they are not sufficient on their own to prevent influenza entirely. Vaccination remains the primary and most effective way to prevent the flu.
Getting the influenza vaccine every year before the flu season starts is the most effective way to prevent influenza. The flu virus undergoes frequent changes, necessitating an annual vaccine update to match the circulating strains and provide optimal protection.
Influenza vaccines do not contain live influenza viruses. The majority of influenza vaccines are inactivated or made from components of the virus, making it impossible for them to cause the flu in vaccinated individuals. Some vaccines, like the nasal spray, may contain weakened live viruses, but they are modified not to cause illness in healthy individuals.
Choice A rationale:
Avoiding vaccination and relying on natural immunity is not the best approach to prevent influenza. Natural immunity may not provide adequate protection against the constantly changing influenza virus, and the risk of severe illness and complications is higher without vaccination.
Choice B rationale:
Washing hands frequently and using alcohol-based hand sanitizer are effective preventive measures for various infections, including the flu. However, they are not sufficient on their own to prevent influenza entirely. Vaccination remains the primary and most effective way to prevent the flu.
Choice C rationale:
Getting the influenza vaccine every year before the flu season starts is the most effective way to prevent influenza. The flu virus undergoes frequent changes, necessitating an annual vaccine update to match the circulating strains and provide optimal protection.
Choice D rationale:
Influenza vaccines do not contain live influenza viruses. The majority of influenza vaccines are inactivated or made from components of the virus, making it impossible for them to cause the flu in vaccinated individuals. Some vaccines, like the nasal spray, may contain weakened live viruses, but they are modified not to cause illness in healthy individuals.
