Nobel prize in medicine awarded to mRNA pioneers – here’s how their discovery was integral to COVID vaccine development

Dr Katalin Karikó and Dr Drew Weissmanhave been awarded the Nobel Prize for their discoveries into mRNA biology. The pair were the first to discover a way of modifying mRNA that allowed it to successfully be delivered to cells and replicated by them. Their discovery was not only integral to COVID-19 vaccine development, but may also lead to the development of many other therapies – such as vaccines for cancer.

Study Adds to Debate about Mammography in Older Women

Studies have shown that routine screening mammography does reduce breast cancer deaths in women aged 40 to 75. But screening also comes with downsides, which include the risk of overdiagnosis and overtreatment. A new study suggests that the risk of overdiagnosis with routine screening mammography is substantial for women in their 70s and older.

CDC Recommends Updated COVID-19 Vaccine for Fall/Winter Virus Season

Vaccination remains the best protection against COVID-19-related hospitalization and death. Vaccination also reduces your chance of suffering the effects of Long COVID, which can develop during or following acute infection and last for an extended duration.  If you have not received a COVID-19 vaccine in the past 2 months, get an updated COVID-19 vaccine to protect yourself this fall and winter.

COVID-19 vaccine boosters are the best defence: Older adults shouldn’t rely on previous infection for immunity

We found that those who had battled the BA.1-2 variant of Omicron in early 2022 had a 30-fold higher risk of contracting the BA.5 variant later in the year. That was exactly the opposite of what we, or anyone, would have predicted. What the findings do tell us is that older adults who have had a previous COVID-19 infection shouldn’t rely on that to protect them against reinfection this fall. To protect against severe illness, keeping booster shots up to date is recommended.
