Scientists from the German Cancer Research Center (DKFZ) recently announced they studied how the human immune response after immunization with the malaria pathogen Plasmodium falciparum (Pf).
Their goal was to find out against which protein components the T helper cells induced in this way are directed. 
Published by the journal Science Immunology on June 10, 2022, this study revealed T helper cells reacted exclusively to the protein sequence of the vaccine strain and showed hardly any cross-reactivity with the naturally occurring pathogen variants. 

The U.S. Centers for Disease Control and Prevention (CDC) reported today the number of pneumonia-related fatalities continues to outpace both COVID-19 and Influenza.
The CDC's National Center for Health Statistics (NCHS) Mortality Surveillance includes data evaluating pneumonia, influenza, and COVID-19 (PIC) fatalities.

Lyme disease has continued to spread worldwide, but there’s little scientific agreement on how common is this tick-borne disease.
To resolve this knowledge gap, the open-access journal BMJ Global Health revealed a pooled data analysis on June 13, 2022, that found more than 14% of the world’s population probably has or has had the presence of antibodies to Borrelia burgdorferi sensu lato (Bb)  infection in the blood.

The cure rate for nonmetastatic rectal cancer has been improving for decades but often includes unpleasant treatments, wrote Hanna K. Sanoff, M.D., M.P.H. in an Editorial published by The New England Journal of Medicine (NEJM) on June 5, 2022.
Recent phase 3 trial findings have increased treatment intensity to include multiagent chemotherapy in addition to radiation therapy before proctectomy is performed.
Such treatment has resulted in a 3-year disease-free survival rate of up to 77%.

According to findings from a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health, people with HIV have a higher rate of breakthrough COVID-19 infections after vaccination than those without HIV.
In the study published in the peer-review JAMA Network Open on June 7, 2022, the researchers analyzed anonymized health records among nearly 114,000 people fully vaccinated with either two doses of mRNA vaccines or one dose of the viral vector vaccine in late 2021.
