H1N1 Swine Flu Vaccine – A Handy Guide – Part II

While in doubt about being infected, does not need the vaccine?

Even in a flu-endemic scenario, cold and other forms of flu-similar sicknesses do tend to circulate. Factually, flu is not the reason behind majority of the flu-similar ailments.

If one has been ailing of flu-similar sickness since the month of April 2009, then one might have contracted the H1N1 swine flu. However, the sole means of corroborating is if one underwent a nasal and throat swab analysis and the laboratory gave a confirmation of the infection.

In case, that did not occur, it is unsafe to presume that one previously had the flu. Particularly when one is at risk of serious flu sickness, it is always prudent to get vaccinated for both the H1N1 swine flu and the seasonal flu. The vaccine is deemed totally safe in those individuals that previously had swine flu.

How is the nasal spray different from the vaccine shots?

The conventional flu vaccines comprise of proteins that are singled out from the flu virus. These detached proteins are non-detrimental in nature. However, its mere presence in the body causes one’s immune system to decipher them and mount a defensive response, which would be highly beneficial in a real case scenario.

The FluMist nasal spray operates on a different mechanism. It is believed to have a diluted version of the live flu virus that is incapable of actually causing the flu. Though, it sounds quite intimidating, but there have been millions of individuals that have got this sort of vaccination quite safely.

The nasal spray is beneficial among children that previously haven’t had flu or received a flu vaccine as it appears to trigger a greater intensity immune reaction as compared to the flu shot.

The downside of using the nasal spray is that in elderly individuals that have had flu or the flu vaccine earlier, it might not be as shielding as the flu shots. This discovery is the outcome of a single study that was conducted during just one flu season. As no one has earlier had H1N1 swine flu previously, the FluMist H1N1 swine flu vaccine is likely to be as effectual among adults as the flu shot is.

With studies revealing that usage of thimerosal as a preservative agent for vaccine is safe, however, is there a substitute?

Miniscule amounts of mercury compound known as thimerosal are used to protect the multi-dose vial of flu shots free from any bacterial contamination. Earlier, when thimerosal was not used with the multi-dose vials there were cases of contamination noted that lead to grave unfavourable episodes.

Detailed studies however failed to detect any lapses that might suggest that thimerosal is not safe. However, if one would not want the presence of thimerosal then there are single-dosages of flu vaccines that do not require and do not have thimerosal amongst their constituents. Even the FluMist nasal spray vaccine does not have thimerosal.

If one prefers a vaccine free of thimerosal then one could verify with one’s supplier for its availability. The state or local health department could also be contacted to gain knowledge of where one can get one.

Is the presence of a substance known as squalene in the vaccine a certainty?

The H1N1 swine flu or seasonal flu vaccines that are available in the United States are free of squalene. Squalene is the innately occurring component of several body processes and is commonly employed in a number of cosmetics due to its easy penetrative property leaving no trace of greasiness or oiliness.
Squalene is additionally a component present in substances known as adjuvants that are known to improve the potency of the vaccine making it function better even in smaller doses.

Millions of doses of such adjuvants were bought in the U.S. in relation to the H1N1 swine flu vaccine to bolster its effectiveness. However, that was not considered essential.  In contrast to the present H1N1 swine flu vaccines, a vaccine having an adjuvant would necessitate specific FDA approval. These kinds of vaccines could be employed during the current year only under ‘Emergency Use Authorisation’ policy of the FDA and no such approval has been issued.

Adjuvants have already received approval in the Europe and other locations and have been deemed safe after being administered to millions, though there might be comparatively slightly more reaction at the prick site in comparison to those vaccines that did not have adjuvants. The swine flu vaccine administered in the United States during the current year would not be having any adjuvants.

From where could one get the swine flu vaccine?

As children are particularly susceptible to the H1N1 swine flu and are more prone to transmitting the infection to others, several states would be providing H1N1 swine flu vaccinations in schools. In certain states, parents have been sent consent slips.

Certain states have additionally planned for providing vaccinations at public locations.

What is the costing for the H1N1 swine flu vaccine?

The U.S. government has bought the vaccine from the producers and is offering the vaccines free of cost. The CDC has requested the suppliers not to charge for giving the vaccine. Even if they do charge, there are many big insurance companies that have stated that they would cover the costs.

Is the H1N1 shot compulsory?

The swine flu vaccines are voluntary for majority of the Americans. Only those in the military (active-duty staff), active-duty National Guard troops, staff from the civilian Defence Department in crucial jobs and health care employees would be required to get vaccinated.
