awk '{if ($1 == "#CHROM"){print NF-9; exit}}' input_vcf_file.vcf

exactly, it is just the number of columns, after substracting the first 9. Moreover, when you do any operation with vcftools, the number of individuals is shown in the log messages ("File contains 2737 entries and 1092 individuals.", "After filtering, kept 1092 out of 1092 Individuals")
