I acknowledged the background you refer to by mentioning both the humoral and adaptive immunity. I did not feel it needed to be spelled out. Let’s not get bogged down in semantics. Vaccination / immunization generates an “alarm button” for the immune system to kick in when it recognizes a foreign structure / epitope. But often (day with flu vaccination), a defensive response is not initiated. “There were 40,414 deaths in the U.S. during the third week of 2018, the most recent data available, and 4,064 were from pneumonia or influenza, according to the CDC data.” (sic) What I am suggesting is an alternative therapy for when the immune-system response is not adequate. It would not be a big issue to administer antibodies directly into the blood compartment to avoid a possible development of a life-threatening situation. It might be worth to engineer and manufacture such antibodies in parallel with developing flu vaccines.

Thank you both; I am new to this site and did not know this facility is already in place.

Thank you very much! I agree. The way you responded should be implemented as a general approach on this site. What I mean that when commenting on a topic, one should "cast a vote" - i.e., saying YES, NO, or ABSTAIN. This way, one would get an overall feel for how the topic / question is being seen - i.e., it would be similar to how a formal debate is usually conducted. Perhaps you can suggest this to this site organizers? I would definitely support this idea. Thanks again.

I have no doubt that getting vaccinated is beneficial. However, the efficacy of vaccinations can be as low as 30%. One of the factors that is essential is the efficacy of an individual's immune system. It varies from person to person, and in some cases, mainly as related to age, it may not function at all, such as in neonates or at old age. Vaccination initiates development of humoral immunity (the body produces antibodies against given antigen), with cell-mediated immunity involving memory T-lymphocytes. However, another way to obtain immunity is to transfer the actual antibodies between individuals. This opens a possibility of immunizing individuals with an inadequate immune system by introducing into their blood stream antigen / diseases-specific antibodies engineered and manufactured for that purpose. Question: Is this option being pursued for flu vaccination? If not, why not?

I posted the initial question; now I see that the ensuing discussion has reached the point of being irrelevant. Is there a way to terminate discussions on this site?

How about all the other components in a pot of paint, such as solvents, surfactants, dyes, etc?

Material Safety Data Sheet (MSDS) for Sodium lauryl sulfate gives the following information: Section 11: Toxicological Information WARNING: THE LC50 VALUES HEREUNDER ARE ESTIMATED ON THE BASIS OF A 4-HOUR EXPOSURE. Acute oral toxicity (LD50): 1288 mg/kg [Rat.]. Acute toxicity of the dust (LC50): >3900 mg/m 1 hours [Rat]. 3MUTAGENIC EFFECTS: Mutagenic for bacteria and/or yeast. May cause damage to the following organs: skin.Hazardous in case of skin contact (irritant), of ingestion, of inhalation. Slightly hazardous in case of skin contact (sensitizer).Special Remarks on Toxicity to Animals:Lowest Published Lethal Dose: LDL [Rabbit] - Route: Skin; Dose: 10000 mg/kgSpecial Remarks on Chronic Effects on Humans: May cause adverse reproductive effects based on animal test data. No human data found.Special Remarks on other Toxic Effects on Humans:Acute Potential Health Effects: Skin: Causes mild to moderate skin irritation. May cause allergic reaction (dermatitis) Eyes: Causes moderate eye irritation. Inhalation: Material is irritating to mucous membranes and upper respiratory tract. May cause allergic respiratory reaction. Ingestion: Causes gastrointestinal tract irritation with nausea, vomiting, hypermotility, diarrhea, and bloating. May also affect behavior (ataxia, somnolence), and cardiovascular system. Chronic Potential Health Effects: Skin: Prolonged or repeated skin contact may cause allergic dermatitis. Ingestion: Prolonged or repeated ingestion may affect the liver. Inhalation: Prolonged or repeated inhalation may cause allergic respiratory reaction (asthma). (From: http://www.sciencelab.com/msds.php?msdsId=9925002) It does make sense not to ingest detergents unnecessarily. Further, there are several other components in washing up liquids that are likely to have additional undesirable effects on health. To rinse or not to rinse? It’s your decision.
