The greatest concern is frequently associated with gain-of-function mutations, which confer novel or increased functionality, and the risk of their release. Gain-of-function research on viruses has been occurring since the 1970s, and came to notoriety after influenza vaccines were serially passed through animal hosts. [citation needed]
A 2013 review, of 1,783 papers on genetically modified crops and food published between 2002 and 2012 found no plausible evidence of dangers from the use of then marketed GM crops. [ 13 ] In a 2014 review, Zdziarski et al. examined 21 published studies of the histopathology of GI tracts of rats that were fed diets derived from GM crops, and ...
CRISPR-Cas9 genome editing techniques have many potential applications. The use of the CRISPR-Cas9-gRNA complex for genome editing [10] was the AAAS's choice for Breakthrough of the Year in 2015. [11] Many bioethical concerns have been raised about the prospect of using CRISPR for germline editing, especially in human embryos. [12]
Off-target genome editing refers to nonspecific and unintended genetic modifications that can arise through the use of engineered nuclease technologies such as: clustered, regularly interspaced, short palindromic repeats ()-Cas9, transcription activator-like effector nucleases (), meganucleases, and zinc finger nucleases (ZFN).

The same survey found that 13% of Americans believe vaccines can cause autism, up from 6% in 2015, and roughly half of Americans are unsure if vaccines cause autism. Just 36% understand that ...

As many as half the people who get meningococcal vaccines have mild side effect which include redness or pain at injection site; small percentage of people develop a fever; These symptoms usually only last 1 or 2 days [2]
Kennedy has had a lot to say about vaccines, more recently saying on the Lex Fridman podcas t in 2023 that “there’s no vaccine that is safe and effective.”
