This year’s vaccine protects against three viruses: the 2009 H1N1 flu virus, the influenza B virus, and the H3N2 virus, which has frequently caused high rates of pneumonia and death.

According to the Consumer Health Reports’ National Poll, some Americans are opting to not get the vaccine. Last year, 45 percent of American adults got the flu-shot, which was a four-percent increase from 2008. But, only 37 percent of the respondents said they would definitely get this season’s vaccine.

So for those that choose not to get the flu vaccine, there are things you can do to keep your immune system strong and resilient.

1. Oscillococcinum- a homeopathic remedy that is very popular among those looking for alternative therapies. Take it when exposed to people that are sick and when traveling.

2. Olive leaf- A potent anti-oxidant and natural antimicrobial for any acute infection. This herb works as an antibiotic, antiviral, and antifungal. I recommend 2 (500 mg) capsules three times/day with food.

3. Elderberry Extract- Studies in Israel have shown this syrup (known as Sambucol) to prevent flu viruses from replicating, thus reducing symptoms. Use 1-2 tsps three times per day. Take this at the first sign of the flu.

4. Vitamin C and bioflavonoids help to prevent colds and flu. You can take this daily during the cold season. Take about 1000-3000 mg daily. If stools become loose, then decrease the dose.

5. N-acetyl-cysteine (NAC)- This natural substance is a form of the amino acid cysteine. For decades it was used in the ER to treat acetaminophen (Tylenol) poisoning. It helped revive the liver by boosting the levels of glutathione in the body. Glutathione is a potent intracellular antioxidant that prevents and helps treat flu symptoms. It is also great for respiratory problems, colds and sinus infections. The dose is 1500-3000 mg daily.

6. Sleep- we all need more.

7. Wash those hands…often.

8. Drink lots of water, 6-8 glasses daily.
