The NVIC is a nonsense site funded mainly by a handful of rich anti-vaxxers, they site actual CDC and NIH data inaccurately and conclude absurd outcomes which the data does not show.

For example - total bunk:

Another 2018 published study found that the influenza virus may be spread simply by breathing (i.e., no coughing or sneezing required) and that repeated vaccination increases the amount of influenza virus released into the air. Study authors reported that “Little is known about the amount and infectiousness of influenza virus shed into exhaled breath. This contributes to uncertainty about the importance of airborne influenza transmission,” and “We show that sneezing is rare and not important for—and that coughing is not required for—influenza virus aerosolization.”

This study also found that a recently vaccinated individual who received the live attenuated influenza vaccine (LAIV) may potentially shed and transmit the virus. According to the study, people who were vaccinated for influenza shed more than six times more virus into the air than those who were not:

“Self-reported vaccination for the current season was associated with a trend toward higher viral shedding in fine-aerosol samples; vaccination with both the current and previous year’s seasonal vaccines, however, was significantly associated with greater fine-aerosol shedding in unadjusted and adjusted models.

In adjusted models, we observed 6.3 times more aerosol shedding among cases with vaccination in the current and previous season compared with having no vaccination in those two seasons.”

More investigation is needed given that annual vaccination may increase aerosol viral shedding and result in reduce vaccine effectiveness. Study authors reported:

“The association of current and prior year vaccination with increased shedding of influenza A might lead one to speculate that certain types of prior immunity promote lung inflammation, airway closure, and aerosol generation. This first observation of the phenomenon needs confirmation. If confirmed, this observation, together with recent literature suggesting reduced protection with annual vaccination, would have implications for influenza vaccination recommendations and policies.”

It is likely possible that after vaccination, a person may become a contagious silent carrier of influenza. A person with symptoms of influenza (i.e. body aches, fever, cough) would likely stay at home. However, a vaccinated individual who is silently contagious would continue to go to public places such as work, school, and stores, and be unaware that they are spreading the virus, even with regular breathing.

In June 2019, the CDC reported that the 2018-2019 seasonal flu vaccine offered no protection against the circulating H3N2 flu strain which emerged in late February and overall flu vaccine effectiveness was reported at only 29 percent. Among adults hospitalized for the flu, the vaccine’s effectiveness against the H3N2 strain was reported at -43 percent. A negative percentage indicates that persons who were vaccinated with the 2018-2019 seasonal flu vaccine were more likely to be hospitalized for flu, than those who were not.

A 2020 study conducted by the U.S. Department of Defense found that the influenza vaccine increases the risks from coronavirus by 36 percent.
