Busting Common Vaccination Myths
“I heard that getting the flu shot can give you the flu.”
False! The flu vaccine cannot give you the flu. It is made from inactivated viruses or pieces of the virus, which cannot cause the illness. Some individuals may experience mild side effects like soreness at the injection site or a low-grade fever, but these are not symptoms of the flu.
| Benefits of Flu Vaccination | Antiviral Medication |
|---|---|
| Reduces risk of flu illness | Can reduce severity and duration of illness if taken early |
| Minimizes flu-related hospitalizations | Prescribed for high-risk individuals and those with severe illness |
| Protects vulnerable populations | Requires a prescription from a healthcare professional |
It is essential to remember that the flu vaccine protects against specific strains of the flu virus, so it is still possible to contract other respiratory illnesses that may have similar symptoms, such as the common cold. However, the vaccine significantly reduces the risk of flu-related complications, hospitalizations, and the overall burden on healthcare systems.
Antiviral Medication for Flu
Antiviral medications can be prescribed by a healthcare professional to help treat the flu and alleviate symptoms. These medications work by inhibiting the replication of the flu virus in the body, reducing the severity and duration of the illness.
Commonly prescribed antiviral drugs for the flu include oseltamivir (Tamiflu), zanamivir (Relenza), peramivir (Rapivab), and baloxavir marboxil (Xofluza). These medications are most effective when taken within the first 48 hours of symptom onset, so it is essential to seek medical advice as soon as possible if you suspect you have the flu.
Antiviral medications can help shorten the duration of flu symptoms by an average of one to two days and may also reduce the risk of developing complications such as pneumonia. However, it is important to note that these medications do not replace the need for preventive measures such as vaccination and good hygiene practices.
| Antiviral Medication | Administration | Possible Side Effects |
|---|---|---|
| Oseltamivir (Tamiflu) | Oral (capsule or liquid) | Nausea, vomiting, headache |
| Zanamivir (Relenza) | Inhaled (using a device called a Diskhaler) | Cough, throat or nasal discomfort |
| Peramivir (Rapivab) | Administered intravenously (IV) | Diarrhea, nausea, headache |
| Baloxavir marboxil (Xofluza) | Oral (single-dose tablet) | Diarrhea, bronchitis |
It is crucial to follow the prescribed dosage and duration of treatment as recommended by your healthcare provider. Not everyone with the flu will require antiviral medication, and individual circumstances will need to be assessed by a healthcare professional.
If you suspect you have the flu or have been in close contact with someone who has tested positive for the flu, it is important to seek medical advice. Your healthcare provider will be able to provide guidance on whether antiviral medication is necessary and appropriate for your situation.
