Alcohol and the Immune System Alcohol Research: Current Reviews

A person undergoing chemotherapy will receive regular blood tests to monitor their neutrophil levels. Regular monitoring can help doctors assess how the immune system is functioning. These hormones may increase the risk of cancer cells becoming resistant to chemo drugs. They may also prevent the immune system from detecting and destroying cancer cells. The flu shot offers protection against several strains of influenza, and each seasonal vaccine is developed to target the most common strains in a given year. The flu shot doesn’t include a live virus, so you can’t get the flu from your shot.

The World Health Organization (WHO) and U.S. surgeon general have warned people to avoid drinking too much alcohol during the COVID-19 pandemic. For those who have a risk factor for COVID-19, like heart disease or diabetes, he recommends drinking Tips for Treating and Living With Essential Tremor Cleveland Clinic even less. And the less sleep a person gets, the higher their risk for getting sick. According to the Cleveland Clinic, once you take a sip of alcohol, your body prioritizes breaking down alcohol over several other bodily functions.


However, excessive alcohol consumption can cause the gut to lose these microbes, thereby compromising or suppressing the immune system. Although excessive alcohol consumption is known to negatively affect the immune system, Messaoudi and her fellow researchers found a surprising effect of moderate alcohol consumption. “Alcohol consumption has increased at home; people are stressed,” Ilhem Messaoudi, PhD, professor of molecular biology and biochemistry and director of the Center for Virus Research at the University of California, Irvine, tells Verywell.

If you were already infected at the time of your vaccination or become infected right afterward, there is still a chance you could get sick with the flu and pass it on to others around you. When you receive your flu shot, you are being given an inactive or synthetic version of the virus, meaning the flu shot does not infect you with the flu. Instead, it exposes your body to inactive viruses so it is able to detect the virus and kill it if you are exposed to the flu. You cannot pass the virus or an influenza infection on to others from the vaccine. Similar to the lack of medication restrictions with the flu shot, there isn’t much to worry about regarding foods and drinks after getting your flu shot.

HIV/AIDS is a disease in which mucosal immunity already is under attack. Bagby and colleagues review substantial evidence that alcohol further disrupts the immune system, significantly increasing the likelihood of HIV transmission and progression. And it’s not just that you’re more likely to get a cold — excessive drinking is linked to pneumonia and other pulmonary diseases. It can also lead to a wide range of health problems, including high blood pressure and heart disease, liver disease, and increased risk of cancer.

Taking care of yourself will help your immune system take care of you.

Here’s what you need to know about how alcohol affects your immune system. A lack of sleep can also affect how long it takes for a person to recover if they do get sick, according to the Mayo Clinic. Below are some answers to frequently asked questions about chemotherapy and the immune system.

Short-term effects of alcohol consumption

B cells mature into plasma cells that produce antibodies, also known as immunoglobulins (Ig), to eliminate extracellular microorganisms and prevent the spread of infection. The adaptive immune response can be distinguished from innate immunity by the capability of generating immunological memory, or protective immunity against recurring disease caused by the same pathogen (Janeway 2008). For example, a 2015 study in the journal Alcohol found that binge drinking can reduce infection-fighting white blood cells known as monocytes in the hours after peak intoxication, essentially weakening your immune system. Alcohol alters the makeup of your gut microbiome — home to trillions of microorganisms performing several crucial roles for your health — and affects those microorganisms’ ability to support your immune system. It seems that drinking alcohol may also damage the immune cells that line the intestines and serve as the first line of defense against bacteria and viruses.

In contrast, moderate alcohol increased frequency of lymphocytes (Figure 1). A second study by Joosten et al. also analyzed gene expression profiles in PBMCs isolated from 24 healthy male subjects who consumed 50mL of vodka with 200mL orange juice or only orange twice daily for 4 weeks during dinner (considered to be moderate). Pathways involving antigen presentation, B and T cell receptor signaling, and IL-15 signaling were altered with moderate vodka consumption (Joosten, van Erk et al. 2012). The most significant change was in glucocorticoid receptor (GR) signaling, which is known to down-regulate immune activity and inflammation by down-regulating NFκB (Pelaia, Vatrella et al. 2003). Indeed, NFκB was down-regulated in the alcohol group compared with the control group (Joosten, van Erk et al. 2012).

To this end, heavy drinkers have been shown to exhibit an increase in both IgA and IgM levels when compared to both moderate and light male drinkers. “Drinking alcohol in large quantities even just for a short period of time — like binge drinking — can be bad for your health and your immune system,” says Favini. Past research shows alcohol consumption leads to more severe lung diseases, like adult respiratory distress syndrome (ARDS) and other pulmonary diseases, including pneumonia, tuberculosis, and respiratory syncytial virus. Chemotherapy can temporarily reduce the number of infection-fighting white blood cells (WBCs). This weakens the immune system, making a person more susceptible to infection.
