Expert Review of Vaccines.
Unless you are fool enough to walk into the room of a known influenza patient without a mask and inhale deeply. The efficacy of live attenuated cold-adapted ca reassortant influenza A H3N2 and H1N1 virus vaccines against experimental challenge with homologous wild-type virus 7 months after vaccination was compared with that of licensed inactivated virus vaccine in seronegative hemagglutination-inhibiting antibody titer less than or equal to 1: Reported rates of adverse events and local reactogenicity are not in excess of those that would be expected with other inactivated seasonal flu vaccines, suggesting that squalene in this vaccine poses no significant risk.
Does it make sense to mandate the flu vaccine. In institutionalized elderly, the vaccine, when given to staff and patients, did not prevent influenza but did decrease pneumonia and all cause mortality PubMed PubMed.
You have make due with the tools at your disposal. The two holes are then sealed with melted paraffin and the inoculated eggs are incubated for 48 hours at 37 degrees Celsius.
Other vaccine production technologies, e. Scientists continue to work on better ways to design, conduct and evaluate non-randomized i. After wild-type virus challenge, live ca virus vaccinees demonstrated resistance at least as great 7 months postvaccination as did inactivated virus vaccinees PubMed.
However, it is not the only problem with the flu vaccine. Flu vaccine trials calculate "effectiveness" during, typically, a 6 month monitoring and "benefit" calculating period but the two week period following vaccination is not included in their calculations.
At this point, the viruses have been weakened or killed and the viral antigen is purified and placed inside vials, syringes, or nasal sprayers. What we do know is that in the last few years, the number of serious reactions reported to VAERS from flu vaccines has been steadily increasing.
Last year during the season, more than U. The Rice method, known as pEpitope pronounced PEE-epih-topewas invented more than 10 years ago as a fast, inexpensive way of gauging the effectiveness of proposed flu vaccine formulations. Cox Professor in Biochemical and Genetic Engineering and professor of physics and astronomy.
The review authors found that in children aged from two years, nasal spray vaccines made from weakened influenza viruses were better at preventing illness caused by the influenza virus than injected vaccines made from the killed virus.
Flu vaccination can reduce the risk of flu-associated hospitalization for children, working age adults, and older adults. MF59, a proprietary adjuvant containing squalene, is included in a seasonal subunit influenza vaccine licensed by the Italian regulatory authority in and subsequently by several other countries.
Vaccination had a modest effect on time off work, but there was insufficient evidence to draw conclusions on hospital admissions or complication rates.
Specific groups This is the most most difficult study to do for the reasons mentioned above. When attempting to make informed decisions about health care, we need to not only consider if a proposed intervention works the benefit ; we also must consider the potential harm of the intervention the risks.
CDC conducts studies each year to determine how well the influenza flu vaccine protects against flu illness. An explanation of U. However, there is evidence to the contrary, as the following article reveals.
REVIV’s Vitaglow Anti-Aging IV therapy contains a high dose of the master antioxidant Glutathione as well as Vitamin C to help detoxify the body from damaging free radicals and improve the appearance of hair, skin and nails.
My boys both got flu shots last year but one of them contracted the flu. His case was fairly mild though, and without a swab to confirm diagnosis I would have assumed minor virus.
Aug 07, · What is the flu shot?
The flu shot is a vaccine given with a needle, usually in the arm. The seasonal flu shot protects against the three or four influenza viruses that research indicates will be most common during the season.
CDC recommends use of. Squalene is a component of some adjuvants that is added to vaccines to enhance the immune response.
A naturally occurring substance found in plants, animals and humans, squalene is synthesized in the liver and circulates in the human bloodstream.
Have you heard that there is a shortage of nurses, which is predicted to get worse as baby-boomers age? It would seem to me that an important question to ask is, “What effect does mandatory flu vaccination have on the shortage of nurses?”.
Another question that comes to my mind is: What effect does the witnessing of vaccine-reactions in their patients have on the nurses’ resistance to. Health news with a focus on fitness news, wellness coverage and living a healthy Southern California life.Efficacy of flu shots
