“Soreness of stomach canker” may increase risk of flu-like symptoms, new study says

SAN FRANCISCO — Vaccination can be a boon for people who get sick from influenza and who have trouble recovering.

A new study published in the British Medical Journal found that vaccination of people with stomach cankers and cough and colds can lower their risk of having flu-related symptoms.

This may be because the virus is harder to kill in the stomach, where there are more cells to spread the virus, said the study’s senior author, Dr. John W. Mascarenhas, a gastroenterologist at Massachusetts General Hospital in Boston.

“A little bit of vaccine may be enough to reduce the risk of being exposed to the virus,” Dr. Mescarenhas said.

The researchers compared the health of people who had a stomach cankering and cough or cold with those who did not have these conditions.

They looked at people who got influenza-related infections in the past, but who were vaccinated with the influenza vaccine and who had no other medical problems.

They looked at those vaccinated with nasal swabs that had been collected at the time of vaccination.

Then, they looked at whether they had any other conditions that were associated with a lower risk of influenza-like illness, including a history of stomach or lung cancer.

Dr. Mervin C. Bouchard, an infectious disease specialist at the University of Michigan in Ann Arbor, agreed that the results are strong evidence that vaccination is protective.

“It’s not just about getting vaccinated, it’s about knowing when to get vaccinated and when to not get vaccinated,” Dr
