Two separate studies published Thursday in the journals Science and Science Immunology found that the highly contagious and potentially fatal measles virus could cause "immune amnesia" by removing antibodies that protected patients from other diseases.
Harvard Medical University, which directs Science Science, examines blood samples from children before and after measles. They found that the virus wiped out 11% to 73% of patients' protective antibodies, putting them at greater risk of viral and bacterial strains against which they had previously been immunized.
This means that measles can effectively override the protection afforded by vaccines against other infections such as influenza or even tuberculosis ̵
1; and measles outbreaks can thus cause spikes in other diseases.
"Imagine your immunity to pathogens is like carrying around a book with pictures of criminals and someone punching a bunch of holes in it," Michael Mina, one of the study's lead authors, said in a media release in [Harvard"Thenitwouldbemuchhardertorecognizethiscriminalifyousawthemespeciallyiftheholesweredrilledoverimportantrecognitionfeaturessuchaseyesormouth"
Patients with measles survivors eventually reclaim those lost ones. immunities – but they must be re-exposed of illnesses to build these protections, as if you have to meet the criminals who have disappeared from your book again, one by one – a long and risky process during which you remain vulnerable to whatever these criminals want to inflict on you.
"The team showed for the first time that measles restores the human immune system back to an immature, baby-like state with only a limited ability to respond to new infections," a press release from the Wellcome Sanger Institute said in a statement. contributed to the study of Science Immunology.
