AlPO 4 ·2H 2 O dihydrate is found as the minerals variscite and meta-variscite. [14] Aluminium phosphate dihydrate (variscite and meta-variscite) has a structure that can be regarded as an assembly of tetra- and octahedral units of phosphate anions, aluminium cations and water. Al 3+ ions are 6-coordinate and PO 4 3-ions are 4-coordinate. [3]
An increasing number of children are undervaccinated, of whom an estimated 13% or more are believed to be so because of parental choice.

Variscite is a hydrated aluminium phosphate mineral (AlPO 4 ·2H 2 O). It is a relatively rare phosphate mineral. It is sometimes confused with turquoise; however, variscite is usually greener in color. The green color results from the presence of small amounts of trivalent chromium (Cr 3+). [5]
The polio vaccines prevented 29 million cases of paralytic polio between 1960 and 2021, compared with a counterfactual world with no vaccines, according to researchers’ estimates.
When Pfizer and BioNTech’s (PFE) COVID-19 vaccine on Monday became the first ever to receive full Food and Drug Administration approval, a slew of vaccine mandates followed. The uptick shows ...
ATC code J07 Vaccines is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. [1] [2] [3] Subgroup J07 is part of the anatomical group J Antiinfectives for systemic use. [4]
Relief and elation over the vaccine program has given way to frustration and disillusionment, as the rollout proceeds at a pace much slower than expected.
